Installation and Commissioning

What is assembly on site?
Our service engineers are able to support you in assembling and installing products on site. Due to our many years of experience we can perfectly judge the risks involved.
The actual assembly of the units can either be done by our qualified engineers our by your own assembly team under DencoHappel supervision. As you may expect from us, we continuously update ourselves with the latest technologies ensuring that the assembly on site is performed with the utmost efficiency.
By outsourcing your assembly on site to DencoHappel engineers you will ensure yourself of having qualified engineers on site who know the product well and who are experienced and specialized in ensuring that our units are assembled using the proper tools and sealing materials. This will result in air tight units with lower risks of performance issues once commissioned.

What is full system commissioning?
Time pressures during construction often mean that building services systems are not properly commissioned and so never give optimum performance. The best option is to
engage DencoHappel Service to commission your system at the outset. Alternatively,
we can carry out retrospective commissioning. The result will be a plant that operates to design specification and is fully able to meet the demands of the end user.
